CROSS REFERENCE OF RELATED APPLICATION

This application is a Divisional application of a non-provisional application, having an application Ser. No. 11/002,944 and a filing date of Dec. 01, 2004 now U.S. Pat. No. 7,108,147.

BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to a sealing valve, and more particularly to a vacuum pump valve which is capable of effectively sealing a particular container in a vacuum manner.

2. Description of Related Arts

Vacuum pumps have widely been utilized to extract air from a food container, such as a plastic bag, so as to create a vacuum environment within the container for preserving the food for a prolonged period of time. The basic steps for sealing a container is pretty simple: first, a vacuum pump is inserted into the container via a vacuum opening; second, a user may turn on the vacuum pump for extracting air within the container, third, the vacuum pump is detached from the container, finally, the vacuum opening should be effective sealed to prevent air going in or out of the container via the vacuum opening.

As a matter of conventional practice, the latter step represents the most important factor in determining the final outcome of the vacuum sealing process. No matter how efficient and effective the vacuum pump is, when the vacuuming process is finished, it has to be detached from the container and the vacuum opening must be effectively sealed in order to prevent re-entering the container again. As a result, if there was substantial re-entering of air, the container would be filled with considerable amount of air which eventually contaminates micro-organisms and bacteria within the container sufficient to deteriorate the food contained in the container.

Conventional vacuum valve for sealing this vacuum opening is generally unsatisfactory in that leakage frequently occurs between the container and its exterior so that air can pass through the vacuum opening and deteriorates the food in the container, which is originally supposed to be preserved for a prolonged period of time.

Conventionally on the other hand, the above-mentioned vacuum pump may be utilized for sealing plastic bags as well as certain specifically designed rigid container. Very often, different kinds of containers utilize different kinds of sealing valves. For example, a sealing valve for sealing a plastic bag may not be suitable to employ in a rigid container so that another different kind of sealing valve is needed. This inevitably increases the manufacturing cost of the sealing valve as well as the respective container as a whole.

Apart from all these, it must also be appreciate that very often, the presence of sealing valve may affect the operation of the vacuum pump and effective creation of vacuum environment within the container. For example, when a plastic bag is being vacuumed and collapsing, a boundary between the sealing valve and the plastic bag may not be fittedly aligned so that a significant amount of air is trapped at the boundary.

SUMMARY OF THE PRESENT INVENTION

A main object of the present invention is to provide a vacuum pump valve which is capable of effectively sealing a particular container in a vacuum manner, so as to retain a vacuum environment within the container for a prolonged period of time.

Another object of the present invention is to provide a vacuum pump valve comprising a suction element automatically operating corresponding with a suction effect of a vacuum pump for allowing effective suction and sealing of the container.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 1, FIG. 2A and FIG. 2B of the drawings, a vacuum pump valve of a container according to a first preferred embodiment of the present invention is illustrated, in which the container has a receiving cavity subject to an interior pressure, and an opening communicating with the receiving cavity. The vacuum pump valve comprises a valve body 10 and a suction element 20.

According to a first preferred embodiment of the present invention, the valve body 10 comprises a sealing platform 11 sealedly attached on the container at the opening thereof, and a guiding sleeve 12 upwardly extended from the sealing platform 11 to form a suction channel 13, wherein the sealing platform 11 has an operation hole 111 formed thereon at a position within the suction channel 13, and at least a through ventilating groove 112 communicating the receiving cavity of the container with an exterior thereof, which is subject to an exterior pressure.

On the other hand, the suction element 20, which is disposed within the suction channel 13 of the valve body 10, comprises an enlarged sealing head 21 adapted to seal on the sealing platform 11 to enclose the ventilating groove 112 thereof, and a guiding shaft 22 extended from the sealing head 21 to slidably mount at the sealing platform 11 at the operation hole 111 to move the sealing head 21 between a releasing position and a sealing position, wherein at the releasing position, where the interior pressure is greater than the exterior pressure, the guiding shaft 22 is upwardly slid along the operation hole 111 to upwardly pull the sealing head 21 apart from the sealing platform 11 so as to allow air in the cavity to be withdrawn through the ventilating groove 112 by the virtue of pressure differential between the receiving cavity and the exterior thereof, as shown in FIG. 2A of the drawings.

On the other hand, when the sealing head 21 is at the sealing position, wherein the exterior pressure is greater than the interior pressure, the guiding shaft 22 is downwardly slid along the operation hole 111 to seal the sealing head 21 on the sealing platform 11 at the ventilating groove 112 so as to retain the container in a vacuum manner, as shown in FIG. 2B of the drawings.

According to the first preferred embodiment of the present invention, the container is embodied as a plastic bag having the receiving cavity which defines the opening wherein the vacuum pump valve is arranged to communicates with the opening so as to selectively allow passage of air therethrough, or alternatively, sealing of that opening to maintain the vacuum effect within the plastic bag.

Referring to FIG. 2A, FIG. 2B and FIG. 3 of the drawings, the guiding sleeve 12 is penetrating through the opening of the container for communicating the receiving cavity with an exterior of the container through the suction channel 13, wherein the valve body 10 further comprises a securing base 14 outwardly extended from a bottom end of the guiding sleeve 12 underneath the sealing platform 11 for sealing at an inner side of the container, such as the sealing bag, at a position that the opening of the sealing bag is sealed around the guiding sleeve 12 so as to sealedly attach the valve body 10 to the sealing bag. Moreover, the sealing platform 11 and the securing base 13 together define a vacuum compartment 113 therebetween within the receiving cavity of the container.

The sealing platform 11 has a plurality of ventilating holes eccentrically distributed thereon adjacent to the operation hole 111 wherein the ventilating holes are formed as a plurality of the ventilating grooves 112 in such a manner that the enlarged sealing head 21 of the suction element 20 is radially extended from the guiding shaft 22 for sealing on the sealing platform 11 at the ventilating grooves 112 so as to block passage of air between the receiving cavity and an exterior thereof.

It is worth mentioning that the suction element 20 further comprises means for retaining the guiding shaft 22 in position when it is at the releasing position. The retaining means is preferably embodied as a blocking latch 23 integrally protruded from a lower end of the guiding shaft 22 to lock up the guiding shaft 22 at the operation hole 111 in a slidably movable manner so as to block a further upward movement of the sealing head 21 when the sealing head 21 is upwardly moved at the releasing position.

In other words, the blocking latch 23 is sidewardly extended from a lower end portion of the guiding shaft 21 to align with an bottom surface of the sealing platform 11 such that when the guiding shaft is upwardly slid along the operation hole 111 at the releasing position, the blocking latch 23 is arranged to bias against the bottom surface of the sealing platform 11 so as stop the guiding shaft 21 from further sliding upwardly which would have led it to be detached from the operation hole 111.

As first preferred embodiment, as shown in FIG. 2A and FIG. 2B of the drawings, the blocking latch 23 is circular in shape and radially and coaxially extended from the guiding sleeve 12 for retaining the valve body 10 in position at the opening, while allowing communication between the receiving cavity and the suction channel 13.

The valve body 10 is adapted for use in conjunction with a vacuum pump which is utilized for withdrawing air from the container so as to create a vacuum effect in the receiving cavity. Accordingly, the guiding sleeve should be shaped and crafted to allow communicating with a pumping nozzle of the vacuum pump such that it is capable of withdrawing air from the receiving cavity of the container via the suction channel 13.

In order to fully seal the container, the vacuum pump valve of the present invention further comprises a retention lock 40 detachably mounted at the guiding sleeve 12 to enclose the suction channel 13 between a locked position and an unlocked position, wherein at the locked position, the retention lock 40 is sealed at the guiding sleeve 12 at a position that a bottom biasing wall of the retention lock 40 pushes the sealing head 21 downwardly to seal on the sealing platform 11 so as to ensure that the suction element 20 sealing on the valve body 10, and at the unlocked position, the retention lock 40 is slidably lifted up to allow the sealing head 21 to be pulled apart from the sealing platform 11 for discharging the air in the receiving cavity of the container. In other words, by attaching the retention lock 40 on the guiding sleeve 12, air is blocked from entering into the suction channel 13 after the container has been sealed.

Referring to FIG. 3 of the drawings, in order to further improve suction features of the present invention, the securing base 14, which is radially extended from the guiding sleeve 12 and adapted to attach on the plastic bag within the receiving cavity, has a plurality of suction grooves 141 indently formed at a bottom surface thereon to communicate the receiving cavity with the vacuum compartment 113 and the ventilating grooves 112 of the sealing platform 11 for guiding the air in the receiving cavity of the sealing bag towards the ventilating groove 112 of said sealing platform 11.

Specifically, the suction grooves 141 are radially extended from a central portion of the blocking latch 23 such that air in the vicinity of the respective end of each of the suction grooves 141 is allowed to pass through the respective suction groove 141 to reach the vacuum compartment 113.

The operation of the present invention according to the first preferred embodiment is as follows:

The retention lock 40 is first opened to allow passage of air with the suction channel 13. After that, a suction nozzle of the vacuum pump should be fittedly engaged with the guiding sleeve 12. The vacuum pump is then turn on for drawing air in the receiving cavity through the ventilating grooves 112 while the suction element 20 is moved by pressure difference to slid upwardly so as to pull the enlarged sealing head 21 above the ventilating grooves 112. As a result, air within the receiving cavity will be gradually withdrawn and the plastic bag collapses. At this stage, the vacuum pump creates a smaller exterior pressure with respect to the greater interior pressure so as to draw air form the receiving cavity to the exterior thereof.

It is important to point out at this stage that when the plastic bag collapses, the suction grooves 141 assists in guiding air at two sides of the receiving cavity to be withdrawn to the suction compartment 113 such that even if the plastic bag collapses to possibly block the central portion of the blocking latch 23, air within the receiving cavity can still to be withdrawn through the suction grooves 231.

When the plastic bag is fully vaccumized, it is to be detached from the guiding sleeve 12. Then, higher exterior pressure (atmospheric pressure) will force the suction element moving towards the receiving cavity having smaller interior pressure to slide downwardly along the operation hole 111 until the enlarged sealing head 21 is moved to seal on the sealing platform 11 at the ventilating grooves 112. At this stage, a user of the present invention may close the guiding sleeve 12 by the retention lock 40 so as to securely seal the plastic bag for a prolonged period of time.

Referring to FIG. 4 and FIG. 5A and FIG. 5B of the drawings, a vacuum pump valve according to a second preferred embodiment of the present invention is illustrated, in which the vacuum pump valve of a container having a receiving cavity subject to an interior pressure comprises a valve body 10′, and a suction element 20′.

The valve body 10′ comprises a sealing platform 11′ sealedly attached on the container at the opening thereof, and a guiding sleeve 12′ upwardly extended from the sealing platform 11′ to form a suction channel 13′, wherein the sealing platform 11′ has an operation hole 111′ formed thereon at a position within the suction channel 13′, and at least a through ventilating groove communicating the receiving cavity of the container with an exterior thereof, which is subject to an exterior pressure.

On the other hand, the suction element 20′, which is disposed within the suction channel 13′ of the valve body 10′, comprises an enlarged sealing head 21′ adapted to seal on the sealing platform 11′ to enclose the ventilating groove 112′ thereof, and a guiding shaft 22′ extended from the sealing head 21′ to slidably mount at the sealing platform 11′ at the operation hole 111′ to move the sealing head 21′ between a releasing position and a sealing position, wherein at the releasing position, where the interior pressure is greater than the exterior pressure, the guiding shaft 22′ is upwardly slid along the operation hole 111′ to upwardly pull the sealing head 21′ apart from the sealing platform 11′ so as to allow air in the cavity to be withdrawn through the ventilating groove 112′ through pressure differential between the interior pressure and the exterior pressure, as shown in FIG. 5A of the drawings.

On the other hand, when sealing head 21′ is at the sealing position, where the exterior pressure is greater than the interior pressure, the guiding shaft 22′ is downwardly slid along the operation hole 111′ to seal the sealing head 21′ on the sealing platform 11′ at the ventilating groove 112′ so as to retain the container in a vacuum manner, as shown in FIG. 5B of the drawings.

According to the second preferred embodiment of the present invention, the guiding shaft 22′ of the suction element 20′ has a diameter smaller than that of the operation hole 111′ so as to define a ventilating clearance between the respective sidewalls of the guiding shaft 22′ and the operation hole 111′ wherein the ventilating groove 112′ is formed as the ventilating clearance so as to communicate the receiving cavity with an exterior thereof for allowing air to pass therethrough.

In other words, when the suction element 20′ is at the sealing position, the enlarged sealing head 21′ is slid downwardly to close the operation hole 111′ so as to seal the ventilating groove 112′ for sealing the receiving cavity of the container.

Furthermore, the valve body 10′ further comprises a sealing ring 15′ disposed between an upper side of the sealing platform 11′ and a lower side of the enlarged sealing head 21′ of the suction element 20′ in such a manner to coaxially align with the operation hole 111′, so as to selectively block the ventilating groove 112′ from communicating the receiving cavity and the exterior thereof.

Specifically, when the suction element 20′ is at the releasing position, the enlarged sealing head 21′ is slid upwardly to move away from the sealing ring 15′ so as to allow the receiving cavity communicating with the exterior thereof via the ventilating groove 112′, as shown in FIG. 5A of the drawings. On the other hand, when the suction element 20′ is at the sealing position, the enlarged sealing head 21′ is downwardly slid towards the receiving cavity so as to block the ventilating groove 112′ at the sealing ring 15′ for sealing the receiving cavity with the exterior thereof.

According to the second preferred embodiment of the present invention, the vacuum pump valve is meant to be use in conjunction with the container which is embodied as a rigid container.

As in the first preferred embodiment, the vacuum pump valve also further comprises a retention lock 40′ comprising an air passage regulator 401′ movably disposed within the suction channel 13′, wherein the air passage regulator 401′ is tubular in shape having an air cavity 4011′ formed therein and a top opening communicating the air cavity 4011′ with an exterior of the valve body 10′. Moreover, the air passage regulator 401′ further has a plurality of through air passage holes 4012′ formed on a bottom wall 4013′ of the air passage regulator 401′ for communicating the suction channel 13′ with the air cavity 4011′. According to the second preferred embodiment, the air passage regulator 401′ is adapted to move between a locking position and an unlock position, wherein at the locking position, the air passage regulator 401′ is sealed at the guiding sleeve 12′ at a position that the bottom wall 4013′ of the air passage regulator 401′ pushes the sealing head 21′ downwardly to seal on the sealing platform 10′ so as to ensure the suction element 20′ sealing on the valve body 10′. In other words, air is not allowed to pass through the air passage holes 4012′ and the ventilating groove 112′ for creating the vacuum environment within the container.

On the other hand, when the air passage regulator 401′ is at the unlock position, the air passage regulator 401′ is slidably lifted up to allow the sealing head 21′ to be pulled apart from the sealing platform 11′ for discharging the air in the receiving cavity. Thus, the air passage regulator 401′ is upwardly slid to create a suction gap between the enlarged sealing head 21′ and the bottom wall 4013′ of the air passage regulator 401′ in such a manner the enlarged sealing head 21′ is now capable of moving to the releasing position and create the ventilating groove 112′ at the operation hole 111′ and the clearance between the enlarged sealing head 21′ and the sealing ring 15′. In such a case, air within the receiving cavity of the container is allowed to be withdrawn through the ventilating groove 112′ and the air passage holes 4012′ to reach an air cavity 4011′ so as to be discharged to an exterior of the container.

Moreover, the retention lock 40′ further comprises a sealing actuator 412′ and a guiding rotor 413′, which is also tubular in shape, provided in the air cavity 4011′ within the suction channel 13′ for operatively moving the air passage regulator 401′ between the locked position and the unlock position in a linear manner.

Referring to FIG. 5A and FIG. 5B of the drawings, the guiding rotor 413′ has at least one guiding track 4131′ spirally formed at an outer circumferential surface thereof wherein the air passage regulator 401′ further has an engaging pin 4014′ protruded from a sidewall of the air cavity 4011′ to sildably engage with the guiding track 4131′ of the guiding rotor 413′. On the other hand, the sealing actuator 412′ is provided on top of the air passage regulator 401′ to drive the guiding rotor 413′ to rotate in a predetermined open direction. Once the guiding rotor 413′ is driven to rotate, the engaging pin 4014′ is arranged to sildably move upwardly alone the guiding track 4131′ so as to move the air passage regulator 401′ upwardly alone the suction channel 13′ to reach the unlock position, where air is allowed to pass through the ventilating groove 112′ and the air passage holes 4012′ for being extracted out of the container.

From the forgoing descriptions, it can be deduced that the operation of the present invention according to the second preferred embodiment is as follows:

Referring to FIG. 5A of the drawings, in order to withdraw air from the container, the sealing actuator 412′ is rotated to drive the guiding rotor 413′ to rotate. Once the guiding rotor 413′ is rotated, the air passage regulator is driven to move upwardly as guided by the guiding track 4131′. A vacuum pump is adapted to engage with the valve body 10′ to create a sucking effect. As such, the suction element 20′ is pulled to move upwardly due to greater interior pressure and air is allowed to pass through the ventilating groove 112′ and the air passage holes 4012′ to reach an exterior of the container.

After the air has been withdrawn from the receiving cavity, greater exterior pressure will force the suction element 20′ moving back to the sealing position. In order to lock the suction element 20′ in position, the sealing actuator 412′ is rotated in a predetermined locking direction which is opposite to the open direction so as to drive the air passage regulator 401′ moving downwardly along the suction channel 13′ at the locking position, as shown in FIG. 5B of the drawings.

In order to retain the suction element 20′ in position within the operation hole 111′, it further comprises two holding arms 24′ upwardly and sidewardly extended from the enlarged sealing head 21′ to align with the bottom wall 4013′ of the air passage regulator 401′ so as to retain the suction element 20′ substantially within the operation hole 111′.

According to the second preferred embodiment of the present invention, the vacuum pump valve further comprises a tubular vacuum separator 60′ mounted within the receiving cavity underneath the valve body 10′ to prevent said air being directly extracted towards the suction element 20′ from the receiving cavity, wherein a vacuum gap is formed between the guiding sleeve 12′ and a top edge of the vacuum separator 60′ for allowing the air to be withdrawn to the suction element 20′ through the vacuum opening, as shown in FIG. 5A of the drawings.

In order to enhance the features of the present invention, the vacuum pump valve further comprises a date indicator 50′ provided on the valve body 10′ to indicate the date of vacuuming by the vacuum pump.

One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting.

It will thus be seen that the objects of the present invention have been fully and effectively accomplished.
